It's pretty well accepted the the Lee was one of the great bolt action battle rifles, but it had one serious fault, the cartridge rim. On a side note if anyone has a tome machine go find the clown who decided not to have a rimless round and give him several hard kicks to the bollocks. Anyway back to bussiness. At the end of the Boer War they decided to find a new rifle and cartridge.
My suggestion is this.
How about before they start the search for a better rifle they decide that as a stop gap they'll switch to a,.303 round that apart from being rimless is identical to the rimmed round, and change the seperate bolt head and extracter to accept the new .303?
